๐ธ ๐น ๐บ there are hieroglyphs too, and these appear often enough to be included.
Shame I can only see squares there. I wonder why. I can see wikipediaโs. Does this work? Two hieroglyphs: ๐๐
Edit: It does, I can read those in my own comment.
Edit 2: Windows issue? I can see them on Android/sync for lemmy.
I can see both your and the original hieroglyphics just fine on my phone using Firefox, and on windows with the same.
Odd thing is, my wife sometimes gets MY emoji and non-standard text as squares, and we have the exact same phone. The only difference between us is she uses the default keyboard.
